Equal periods of sun-up and sun-down are all near March 21 and September 21,
everywhere on earth, including the equator.
Those days are often called the "equinoxes", but the equinoxes are actually the
points in the sky where the sun appears to be located on those days.
At the "equinox"; "equi-" from "equal", and "nox" from the Latin word for "night". The equinoxes are generally on March 21 and September 21 each year, plus or minus one day because of the cycle of leap years. The US Naval Observatory has a web site for "Earth's Seasons" at which you can see the precise times of the solstices and equinoxes.
One of them is named "March 21st", and the other is named "September 22nd".
They are the days during which the sun appears to reach the two points among the stars
known as the "equinoxes".
days and nights are of equal duration during an equinox.An equinox occurs twice a year, when the tilt of the Earth's axis is inclined neither away from nor towards the Sun, the center of the Sun being in the same plane as the Earth's equator. The term equinox can also be used in a broader sense, meaning the date when such a passage happens. The name "equinox" is derived from the Latin aequus (equal) and nox (night), because around the equinox, the night and day are approximately equally long. It may be better understood to mean that latitudes +L and -L north and south of the Equator experience nights of equal length.
At an equinox, the Sun is at one of two opposite points on the celestial sphere where the celestial equator (i.e. declination 0) and ecliptic intersect. These points of intersection are called equinoctial points: classically, the vernal point and the autumnal point. By extension, the term equinoxmay denote an equinoctial point.
An equinox happens each year at two specific moments in time (rather than two whole days), when there is a location on the Earth's equator where the center of the Sun can be observed to be vertically overhead, occurring around March 20/21 and September 22/23 each year.
When day and night are equal around the world (North and South Hemisheres) it is called a equinox. In a year that happens twice, once in the Spring which called a Spring Equinox and once in the Fall which is called a Fall or Autumn Equinox. Spring Equinox occurs on March 21 and Fall or Autumn Equinox occurs September 22
The equinox, which is on March 21 and September 21 (plus or minus one day, depending on the cycle of leap years) each year.
During the spring and autumn equinoxes, March 21st and September 21st.
During the equinoxes, day and night have almost the same length.
Day and night are equal all over the world at the vernal and autumnal equinoxes.
Day and night are of equal length throughout the year at the equator.
The length of day and night is equal at the Vernal and Autumnal equinox.
there isent a dade. but here in miami 6:00 am is night and 6:00pm is night too
Any place on earth that lie on the equator will have equal day and night time.
At the two equinoxes (about 22 September and 20 March).
Day and night are of equal length throughout the year at the equator.
An equal day and night occurs twice per year on the summer and winter equinox.
no, day is actually longer
Yes, during an equinox the length of the day and the length of the night are actually the same.
During the Autumn equinox the length of the day and night are nearly equal. The length of the day on the equinox is approximately twelve hours.
Saturday
Equinox
yes
equal day and night
The length of day and night is equal at the Vernal and Autumnal equinox.
The length of day and night is equal at the Vernal and Autumnal equinox.
In Sanskrit, "vishu" typically refers to the equinox, where day and night are of equal length. It is also associated with the Hindu festival of Vishu, celebrated in Kerala, India to mark the new year.
